Struct ElevatorShakeState 

pub struct ElevatorShakeState { /* private fields */ }

Frame-driven elevator rumble: scrolls the background up/down by ±pixel_offset, iterations × 2 frames, a rattle cue each iteration, then a single arrival ding.

Implementations

impl ElevatorShakeState

pub fn new(params: ElevatorShakeParams) -> Self

pub fn params(&self) -> ElevatorShakeParams

pub fn total_frames(&self) -> u16

Total frames of the shake.

pub fn tick(&mut self) -> Option<ElevatorShakeSfx>

Advance one frame. Returns ElevatorShakeSfx::Rattle at the start of each 2-frame iteration and ElevatorShakeSfx::Arrive on the final frame.

pub fn is_done(&self) -> bool

pub fn offset_y(&self) -> i32

Current background scroll offset (±pixel_offset). The first iteration scrolls negative.
